The imaging gamma-ray telescope COMPTEL, capable of detecting gamma rays in the 1 to 30 MeV range, is one of four experiments onboard NASA's Gamma-Ray Observatory GRO. Besides its primary objectives COMPTEL will

Utilizing data fromNASA’s Fermi Gamma-ray Space Telescope, researchers discovered a unique energy peak in the aftermath of the brightest Gamma-Ray burst ever seen, suggesting the annihilation of electrons and positrons. This finding provides new insights into the behavior of cosmic je...
Previous work has shown that the kilonova associated with gamma-ray burst 230307A is similar to kilonova AT2017gfo (ref. 9), and mid-infrared spectra revealed an emission line at 2.15 micrometres that was attributed to tellurium. Here we report a multi-wavelength analysis, including ...
The burst also provided a long-awaited inaugural observing opportunity for a link between two experiments on the International Space Station – NASA’s NICER X-ray telescope and a Japanese detector called the Monitor of All-sky X-ray Image (MAXI). Activated in April, the connection...
new black hole formed within the heart of a collapsing star. In this illustration, the black hole drives powerful jets of particles traveling near the speed of light. The jets pierce through the star, emitting X-rays and gamma rays as they stream into space. Credit: NASA/...
The brightest gamma-ray burst ever seen as observed by the Swift X-Ray Telescope around an hour after it erupted.(Image credit: NASA/Swift/A. Beardmore (University of Leicester)) One of the most remarkable GRBs observed to date is known as the "brightest of all time," or BOAT, GRB. ...
The eruption, which is classified as a gamma-ray burst(GRB), and designated GRB 130427A, occurred just after 3:47 a.m. EDT ( 0747GMT) on April 27, U.S. space agency NASA said in a statement on Friday. NASA's Fermi Gamma-ray Space Telescope recorded one gamma ray with an energy ...
NASA's Goddard Space Flight Center and Adam Goldstein (USRA) The brightness of this event really can’t be exaggerated, but we actually can’t even directly measure the exact intensity with which it hit. After traveling for 1.9 billion years to reach Earth—oddly enough, making it on...
